User Defined Functions (UDFs) for Eulerian Multiphase Flows in Ansys Fluent Software

User-defined functions (UDFs) allow you to customize Ansys Fluent^® fluid simulation software and enhance its capabilities. In this course you will learn the UDF specifics for Eulerian Multiphase flow simulations.

Prerequisites:

• Ansys Fluent Beyond the Basics course.
• Ansys Fluent Multiphase Flow Modeling course.

Learning Outcomes:

Following completion this course, you will be able to:  

• Explain how multiphase-specific UDFs differ from single-phase-specific UDFs.
• Access phase-specific data using data access macros.
• Retrieve multiphase specific domain or thread pointers that are not passed by DEFINE macros.  
• Use the general purpose DEFINE macros within different multiphase models.
• Explain the different utility and looping macros available for multiphase UDFs.

Please note: These training materials were developed and tested in the 2024R1 release.
